Threefold increase in revenues from lease payments related to our Refined Coal ("RC") facilities. In the quarter, RC facilities operated by ADA's Clean Coal Solutions, LLC ("Clean Coal") generated $13.3 million in credits to be used to offset future taxes.

A 40% increase in Emission Control ("EC") revenues. EC backlog as of December 31, 2012 increased to $25.3 million, up from $4.5 million at June 30, 2012 and $736,000 at December 31, 2011.

Consolidated gross margin of $4.6 million, or 7% of revenues compared to $4.7 million or 19% of revenue in 2011. The lower margin percentage in 2012 is due to inclusion of coal purchases and sales and operating costs associated with RC facilities operated for Clean Coal's own account ("retained tons"). 2012 fourth quarter gross margin excluding coal sales and purchases and operating costs for retained tons was 69%.

For the 4th quarter, our net loss was $5.4 million or $0.54 per diluted share as compared to a net income of $17.2 million or $1.90 per diluted share for 2011 which included a non-cash $20.0 million gain for the settlement of an indemnity claim.

OVERVIEW OF 2012 RESULTS

An 83% increase in revenues from lease payments related to our RC facilities. In 2012, RC facilities operated by Clean Coal generated $38.6 million in credits to be used to offset future taxes.

Gross margin of $20 million or 9% of revenues compared to $24.4 million or 46% of revenues in 2011. The 2012 gross margin excluding coal sales and purchases and operating costs for retained tons was 74%.

For the year, our net loss was $13.1 million or $1.31 per diluted share as compared to a net loss of $22.8 million or $2.85 per diluted share for 2011.

2012 OPERATIONAL ACHIEVEMENTS, OVERVIEW OF SEGMENTS & OUTLOOK

Dr. Michael D. Durham, President and CEO of ADA stated, "In 2012, we achieved a number of important milestones that will serve as the foundation for our growth in 2013 and beyond. Clean Coal, ADA's joint venture with NexGen Resources Corporation and an affiliate of The Goldman Sachs Group, Inc., began operating six additional RC facilities and leased two of these facilities to two different refined coal investors. We also achieved qualifying emissions for our new M-45-PCTM technology for pulverized coal (PC) boilers, which greatly expands the market for several remaining RC facilities to include many larger power plants. In the Emission Control segment, we acquired the assets of Bulk Conveyor Specialist Inc. and Bulk Conveyor Services, Inc. (collectively "Bulk Conveyor") through our wholly owned subsidiary BCSI, LLC, which has expanded our Dry Sorbent Injection ("DSI") capabilities and created opportunities to win fleet-wide orders from major utilities for both our DSI and Activated Carbon Injection ("ACI") equipment.

Dr. Durham continued, "Each of our segments reported quarter-over-quarter improvements in the fourth quarter of 2012. Thus far in 2013, we are continuing to see very good progress in our two major business areas, Refined Coal and Emission Control. We will maintain focus on executing on opportunities that we expect will create significant revenue growth and cash flows for the Company over the coming years. We are positioning ourselves for continued long-term success and are developing technologies for expected future markets.

Refined Coal

Total RC revenues in the 4th quarter were $61.2 million consisting of $9.8 million in revenues from leasing four RC facilities and $51.4 million related to the resale of coal for RC facilities operated by Clean Coal. Gross profit for the segment was $3.2 million or 5% of total revenues compared to $4.1 million and 20% in 4Q11 reflecting the higher tonnage treated by RC facilities retained by Clean Coal. Commenting on the outlook for Refined Coal Dr. Durham noted, "With the recent restructuring of the agreements with an affiliate of Goldman Sachs for our two longest operating RC facilities and the February 2013 closing of the sale of an RC facility to a third financial investor, our RC business is back on track with expected growth plans after several months of delays. We expect that the recent resumption of the issuance of Private Letter Rulings for Section 45 RC requests should assist with timely closing of contracts for a number of additional RC facilities throughout this year and into 2014."

Emission Control

EC revenues in the fourth quarter of 2012 were $4.4 million, up 40% from the same period in 2011 due mainly to increased equipment and consulting revenues as the power industry is reacting to finalization of the MATS rule.

Dr. Durham noted, "Finalization of the Mercury and Air Toxics Standards ("MATS") rule in April 2012, is creating significant market opportunities for the low-CAPEX technologies that ADA provides. We are expecting that the MATS could generate market opportunities in excess of $1 billion for ACI and DSI systems, of which we expect to maintain a combined market share of 35%. This would generate over $300 million in revenues for ADA over the next three years. We are pleased with our wins in the 4th quarter of 2012 and the recently announced awards for DSI and ACI systems so far in 2013. With these new contracts, ADA has received awards for DSI and ACI systems with a potential total value of over $50 million. In addition to these awards, ADA has active bids totaling over $125 million for ACI systems and over $160 million for DSI systems. The market for equipment to meet the federal MATS rules continues to accelerate and we expect that additional contracts for DSI and ACI systems will be awarded soon."

CO2 Capture

CO2 Capture revenues in 4Q12 increased 55% to $1.9 million for the quarter due to timing of scheduled activities. As of December 31, 2012, ADA had DOE contracts in progress, including anticipated industry cost share, totaling approximately $12.7 million as of December 31, 2012. The Company expects to recognize approximately $9.7 million from these contracts in 2013 and the balance through 2014.

Dr. Durham went on to say, "ADA's work continues on a $20.5 million program supporting the development of our re-generable solid-sorbent technology to capture carbon dioxide from coal-fired power plants and industrial sources. We have initiated the fabrication and construction phase of a 1MW Carbon Dioxide ("CO2") Capture Pilot Plant with testing scheduled for 2014. We are also evaluating alternative applications for the carbon capture technology that could have market potential ahead of regulations on power plants such as enhanced oil recovery and treatment of landfill gas."

BALANCE SHEET HIGHLIGHTS

As of December 31, 2012, ADA had cash and cash equivalents totaling $9.7 million compared to $40.9 million at year-end 2011 with cash decreases primarily reflecting capital outlays for leasehold improvements, property and equipment additions, a payment related to a litigation settlement, RC facility related costs, repayment of the line of credit held by Clean Coal, increases in our staff levels to support the anticipated growth, and the acquisition of Bulk Conveyor assets by our subsidiary, BCSI, LLC.
